Question

What is the maximum speed of a violent tornado?
A. 50 km/hr
B. 100 km/hr
C. 200 km/hr
D. 300 km/hr

Answer 1

Hint: Extreme weather or extreme climate events includes unexpected, unusual, severe, or unseasonal weather; weather at the extremes of the historical distribution. Extreme events are frequently characterized as occurring in the most unusual 10 percent of a location's weather history, and one such weather condition is a tornado.

Complete answer:
Let us see what a tornado is: A tornado is a tiny column of violently rotating air that forms inside a convective cloud and comes into contact with the ground. Tornadoes are most common in the spring and summer in the mid-latitudes of both the Northern and Southern Hemispheres, when thunderstorms are present. These swirling air vortices can produce the world's fiercest winds.

Tornadoes are caused by the thunderstorms being extremely large, unstable and with wind shear in the lower region of the atmosphere. Instability refers to the hot and humid conditions in the lower atmosphere and cooler conditions in the upper atmosphere. Because of the difference in vapour pressure between hot and cold air, hot air rises above and cool air falls below.

Extreme weather has significant impacts on human society as well as natural ecosystems.The violent tornados are the worst type of tornados. Wind speeds of more than 200 miles per hour are common in strong tornadoes. Tornadoes with wind speeds over 200 mph. A well-anchored, firmly constructed home can only be levelled by strong tornadoes. Fortunately, only around 2% of all tornadoes reach speeds of 200 mph or higher.

Hence the correct answer is option D.

Note:Do not get confused between tornadoes and cyclones. There are 2 different weather conditions. The major difference through which we can make out if it is a tornado or a cyclone is that A tornado is a violent, twisted funnel of high-speed wind, whereas A cyclone is a huge and powerful storm and has large diameters.
